In the wild, reptiles love to bask on rocks and stones as it provides them a great opportunity to absorb infrared A & B (from the sunlight) and infrared C from the stone releasing stored heat. Our Zen Cave features a slatestone basking spot on top. This unique feature mimics nature by absorbing heat from the basking bulb and releasing the heat as infrared C. The cave also features a hiding spot for your pet. It'll become a favorite perch for your heat-loving reptile!
